i shorted out which i thought was the power s

i shorted out what i thought was the power supply so i took out the power supply from another computer and put it in the the one that wouldn't start. that did not work so i put it back in and the other computer wouldn't start. i bought a another motherboard and power supply and everything is working fine. if i put my old motherboard back into the case and the new power supply can i burn anything out

Really hard to tell. Usually you can't easily burn out a power supply. A motherboard is easy to destroy. At this point, without any advanced testing tools I guess you have no choice but to trial and error by using the smoke test.

1/3 of highway deaths are caused by drunks. The rest are by people who can't drive any better than a drunk.

I agree with the above.To get UL listing (and/or equivalent approval), the power supply must not be able to burn your house down. This means that it does not matter if a fusable link, an electronic component, a circuit breaker, or an old fashion fuse breaks the circuit to stop the current flow to prevent a fire, it just MUST do it consistently. A quality product should be made to survive this to be used again, but cheap is cheap, and they may be able to sell you another one some day.
